This is the length (in bytes) of the data portion
in the packet that you want to compare.
The Mask is applied to the data portion before
comparing the result against the Value to
determine a match. It is specified in
hexadecimal, and it takes two hexadecimal digits
to represent a byte i.e., Length is 4, therefore
there are 8 hex numbers.
Enter the value (in hex) to compare with the data
portion.
This setting logs all packets that match these
